Promote muscle growth

Increase and/or maintain levels of red blood cells in the body

Enhance anabolism or tissue building (including muscle)

Inhibit or reduce catabolism or destruction/damage of muscle cells and fibers

Improve sperm manufacture and maturity

This can be difficult to achieve depending on experience, the form of testosterone, the quality of the testosterone, and of course, the ester variants.

Bodybuilders should be aware that esters typically peak roughly 48 hours after an injection. There is a difference in how long the esters remain in the body due to its specific half-life.

Even so, the half-life of a drug is also influenced by a number of factors:
